Answer:
length = 22 inches
width = 8 inches
Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
Perimeter = 60 in
The statement
the length of a rectangle is 6 inches more than twice it's width is written as
l = 6 + 2w
Substitute the statement into the above formula
That's
60 = 2( 6 + 2w) + 2w
60 = 12 + 4w + 2w
6w = 60 - 12
6w = 48
Divide both sides by 6
w = 8
Substitute w = 6 into l = 6 + 2w
That's
l = 6 + 2(8)
l = 6 + 16
l = 22
The dimensions are
length = 22 inches
width = 8 inches
Hope this helps you
